To all whom it may concern: A

Be it known that I, ALBERT CARO, citizen of the United States, residing at Maywood, inthe county of Cook and State of Illinois, have invented certain new 'and useful Improvements in Warming-Ovens;oand I do hereby, declare `thegfollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to `which it appertains to make and use the same. l

My invention relates to improvements in warming devices and has `particular refer-` ence to an improved hot air warming oven, or heating cabinet.

The object of my invention is to provide a warming oven of simple construction for use in conjunction with the usual hot air pipes of a hot air furnace; which shall be capable of being mounted within the wall of the room where it is installed; which shall elflciently make use of the rising hot air and which shall be ornamental in appearance adding to ratherlthandetracting from the appearance of the room. A further object of my invention is to provide a warming oven of the kind described which shall also serve as a hot air register for the room in which it is placed, emitting the hot air into the room after it has heated the oven.

My` invention consists in a hot 4air warming oven adapted` to be Vmounted upon a hot air pipe of a hot air furnace and adapted to be placed in the wall of the room when it is installed, the oven having double or hollow walls in which the hot aircirculates.

My invention alsof consists in a .doublewalled hot air warming oven through which a small percentage ofthe air, by which the oven is heated, is permitted to pass through the oven itself to heat `the contents thereof, the oven having hollow walls in which the hot aiicirculates.` h invention also `consists in the several features of construction and in the arrangements and combinations of arts by which I am enabled to attain the above mentioned and other objects and all as hereinafter described and particularlypointed out in the appended claim.

` Application filed February 12, 1916. Serial No. 78,032. o i

My invention will be more readily understood by reference to the accompanying drawings forming part of this specification in which:

Figure 1* is a front elevation of a warming oven constructed in accordance with my invention and shown in conjunction with a hot air heating pipe, a portion of the wall being broken away to best illustrate the invention;

Fig. -2- is a vertical central section on the line 2-2 of Fig. 1-5

Fig. -3- is a horizontal section on the line 3`-3 of Fig. Q -g and Fig. is a view similar to Fig. --Seq illustrating a slight Inodication of my invention.

In said drawings, A represents a hot air pipe or conduit which usually rises through the wall B and is vadapted to deliver `hot air into a room, in the instance illustrated, through the wall register` C located near the floor of the room in the usual manner. Usually the hot air pipe `terminates at the top of the register though it could be eX- tended upward through the wall to a room above. l i p I provide the hot `air pipe A with an upward extension or nozzle D preferably within the wall B and I provide a warming oven E of peculiar construction with a down wardly extending nozzle F adapted to telescope upon the nozzle D and whereby hot air` can be delivered from the pipe B` to the oven E.

My` improved oven is preferably rectangular in shape, being taller than it is broad and is adapted to be placed in Athe wall above the hot air pipe A and, as has been explained, `receive hot air therefrom. Instead of permitting the hot air to come directly intocontact with the contents of the oven, I prefer to make theoven with hollour walls G on all of its sides except the front, through which thehot airis free to circulate and thereby heat the oven and its contents. I preferably make the oven deeper from front to backthan the depth of` the wall where it is placed so that the forward portion H of the oven projects from the wall asclearly causing a free and rapid circulation of the p hot air through the walls of the oven and permitting the escape of the hot air into the` room for the heating thereof. By means of this construction, I am enabled, in some situations, lto dispense with the register C e11- tirely. I prefer to providethe vregister' AC with a controlling device K made in the usual manner of a series of movable slats L andi :also provide theagrated openings J with similar controlling Adevices M. By means of these controlling devices, I am en abled to govern .the degree of heat which I wish in the oven and also to govern inde pendently the 'flow ofhot air into the room from the hot air pipe A. I sometimes provide the upper end of the oven with a nozzle N adapted to receive the lower end of a conduit O by `which hot :air may be directed to a room above after it has served its purpose of heating the oven, the nozzle communicating with the hollow walls of the oven. Preferably. I divideV the oven vertically by means `of a shelf P which is a flat metallic plate removably supported on ledges Q ksecured to the side wal-ls of the oven.

-I prefer to lbuild the loven itself in two y parts, one partR consisting of the hollow top, bottom, backv and sidewalls with the two nozzles, and adapted tto be placed in position in the wall of the building while the 'building is being constructed, and the liront portion H thereof being adapted to project outwardly beyond the `face S of the wall B as shown in Figs. -2-- and -i8-. The yother part T of the oven constitutes the `front androlnprises a telescoping rectangular frame U adapted to be received upon the projecting part of 'the main part R and provided with a door frame or cover V A hav-ing an ornamental appearance as shown in Fig. A1-Q. The frame V is provided with rearwardly inclined flanges WV adapted to'project rearwardly and vcontact with the face S of the wallB, being provided with a marginal flan e W1 4adapted to lie flat against the face o the wallV when the part T is in position. The grated openings J are formed in the sides Vof this cover part, theouter shell of the double walls of lthe oven being cutaway 4at these points to aallowthe 14hot air to escape from the walls *ofthe `oven through saidgrated openings J.

The frame V also constitutes a frame for a door X by which I close 'the oven. yThe door X is mounted upon the frame V by hinges Y and is provided .with 'a latch 1Z by which it `canbe held closed. 1 The door is walls are finished, the cover or front part T isplaced in position telescoped upon the projecting portion of the part R and secured against easy or inadvertant 'removal 4by bolts or; screwsi T1 at top and bottom, suitable registering holes being provided for the bolts.

-Under some circumstances, I desire'to permit a small percentage of the `lrot lair to pass through the oven itself, and for-this purpose I provide a nunrber ofsmali openings E1 inthe bottomof the inner v'shell of the oven through which -the hot air can escape into the lower 'part of thebven. I prefer that these openings'shall be-"arralged at the rear part ofthe floor of the oven'and I` arrange them in a transverse row as shown. i In order 'to permit a continuous escape of the hot rair through said openings lil1L when the `'door X :is closed, I provide a draft opening X1 in the upper partofthe door and I provide anadjustable 'damper X2 for said opening X1, by means of vwhich I vcan regulate the flow ofhot air through the oven, at timesclosing the opening 1X1 and thus stopping the flow entirely, and jat other times permitting'moreor `less air to escape from ythe oven and thus more @rless to enter through said openings El: v

In Fig. 4E-3 I have illustrated amodied form v'of oven." In this case,*I'h`ave omitted the Vgrated openings J, makingthis part vof; the 'cover V 'solid and depending upon the natu-ralcirculation of the hotair vthrough the hollow walls of` the oven )for the heating thereof. V

While `my improved oven might 'be Aarranged for use in othensituations' and-.in conjunction with morev than one hot air pipe, I have'chosen to illustrate :mydinvention `as connected to asingle fhot airpipe; i

rising through the wall'.

It will now be clear that jIhave provided a very simplewarmingoven for 4,use fin conjunctionwith the usual hota'irV pipes of a heating system; thatvit' is neat in" "ap-4 pearance, thatitcan 'be made to serve 'the purpose of 'a warming oven and allot air register and that it is simple inv construceliicient.

y I claim as my linvention In a devicey of the 'kind described, a hollow walled compartment open "at i'tsfron't adapted tobe mounted in a wall 4andfadapted to be connected at itslo'wer end l)to a tion, easyto install and very desirablejland u mesma? 10 tion between the space beneath said openings and the hollow Walls of said compart ment to which hot air can How from said hollow walls out through said openings.

In testimony whereof I have signed my name in presence of two subscribing witl5 nesses.
